19.4.3
Development Support Status Register (DSSR)
This register is accessible only when the TPU is in test mode; see
Section 19.4.14, “Factory Test
7:8
FRZ
FREEZE assertion response. The FRZ bits specify the TPU microengine response to the IMB3
FREEZE signal
00 Ignore freeze
01 Reserved
10 Freeze at end of current microcycle
11 Freeze at next time-slot boundary
9
CCL
Channel Conditions Latch. CCL controls the latching of channel conditions match recognition
latch (MRL) and transition detect latch (TDL) when the CHAN register is written. Refer to the TPU
Reference Manual (TPURM/AD) for further information.
0 Only the pin state condition of the new channel is latched as a result of the write CHAN register
microinstruction
1 Pin state, MRL, and TDL conditions of the new channel are latched as a result of a write CHAN
register microinstruction
10
BP
Breakpoint enable for microprogram counter (
µ
PC)
0 Breakpoint not enabled
1 Break if
µ
PC equals
µ
PC breakpoint register
11
BC
Channel breakpoint enable
0 Breakpoint not enabled
1 Break if CHAN register equals channel breakpoint register at beginning of state or when
CHAN is changed through microcode
12
BH
Host service breakpoint enable
0 Breakpoint not enabled
1 Break if host service latch is asserted at beginning of state
13
BL
Link service breakpoint enable
0 Breakpoint not enabled
1 Break if link service latch is asserted at beginning of state
14
BM
MRL breakpoint enable
0 Breakpoint not enabled
1 Break if MRL is asserted at beginning of state
15
BT
TDL breakpoint enable
0 Breakpoint not enabled
1 Break if TDL is asserted at beginning of state
